What Does the P0420 Code Mean for Your 2010 Honda CR-V?

AvatarByCarl Frisch

The 2010 Honda CRV P0420 is a diagnostic trouble code that indicates a malfunction in the catalytic converter system. This code is triggered when the engine control module (ECM) detects a discrepancy between the readings from the front and rear oxygen sensors. The oxygen sensors measure the amount of oxygen in the exhaust stream, which helps the ECM determine how much fuel to inject into the engine for optimum performance. When the ECM detects an imbalance between these two readings, it sets this trouble code to alert you that something is amiss in your catalytic converter system. Common causes for this code include a faulty catalytic converter, faulty oxygen sensors, or an exhaust leak.

Maintenance Tips for Honda CRV (2010)

Owning a Honda CRV (2010) is a great investment, and keeping it running smoothly requires regular maintenance. Depending on the age of your vehicle, you may need to perform maintenance more often than others. Here are some tips for keeping your Honda CRV in top condition:

Oil Change and Filter Replacement

Regularly replacing the oil and oil filter in your Honda CRV is essential for keeping it running well.

To check your transmission fluid level, locate the dipstick under the hood of your vehicle and pull it out. If the fluid is low, top it off with new fluid until it reaches the full mark on the dipstick.

Tire Rotation & Pressure Checkup

Your tires are one of the most important components of your vehicle, so it’s important to keep them in good condition. Tires should be rotated every 6 months or 6,000 miles (whichever comes first) in order to ensure even wear and tear over time.
